A Shark’s Sixth Sense around their head called ampullae of Lorenzini. These are jelly filled pores that go down to the nerve receptors at the base of the dermis. They are specialized electroreceptor organs that allow the shark to sense electromagnetic fields and temperature changes in the water column.

Webb2 maj 2013 · Elasmobranchs can detect minute electromagnetic fields, <1 nVcm –1, using their ampullae of Lorenzini. Behavioural responses to electric fields have been investigated in various species, sometimes with the aim to develop shark deterrents to … WebbSharks are much more sensitive to electric fields than electroreceptive freshwater fish, and indeed than any other animal, with a threshold of sensitivity as low as 5 nV/cm. The collagen jelly, a hydrogel, that fills the ampullae canals has one of the highest proton conductivity capabilities of any biological material.
Webb11 maj 2024 · Sharks have been known to be sensitive to electromagnetic fields for quite some time – which made researchers suspect for years that the cetaceans may be using it to navigate. While the hypothesis isn’t new, the latest study conclusively confirms the theory. Are these abilities inherited? Webb27 maj 2024 · Sharks, however, can still detect their presence by sensing their body systems’ electricity, and can dig them up for a meal. This electromagnetic sense is also helpful when it comes to long-distance open-ocean navigation. Not only are there no street signs in the middle of the Pacific, there aren’t any landmarks.
WebbAmerican Scientist Webbthe shark to sense electromagnetic fields and temperature changes in the water column. These organs allow sharks to find prey at a very close range by sensing the weak electrical fields produced by animals in the ocean. These organs also sense the Earth’s Elec-tromagnetic field , allowing the sharks to use this for homing and migration.
